Single General Instruments 8500 lC contains most of electronics needed for pong, hockey, squash, or practice games using screen of TV set. Desired game is selected by grounding one of pins 20-23. Connect ball, player, and score outputs to four-input 0R circuit to generate composite video for com bining with sync output. Final output can be fed directly to video amplifier of TV set or fed to suitable RF modulator. Sound output is fed to Ioudspeaker through transistor audio amplifier.No connection on pin 5 gives two rebound angles, while grounding gives four rebound an gles. Open pin 7 gives fast speed, and grounding gives slow speed. 0pen pin 13 gives small bats, and grounding gives large bats.-D. Lan-caster, CMOS Cookbook, Howard W.
